LIFTIN G JACK.

i Application led January This invention relates to improvements inlifting jacks, having for lan object to provide a lifting jack soconstructed as to render the same especially advantageous for use inreplacing worn bearings in the journal boxes of railway cars, wherebythe box maybe elevated independently vof the car Wheel and its axleinorder that ready access may be had `to thel worn bearing to effectitsr removal, and likewise, that a 'new bearing kmay be conveniently andproperly placed therein. y

yAnother and equally important object of the invention is to provide thejack with a novel form of anchoring leg' adapted kto have adjustablebearing upon ,an` adjacent portion of a car wheel whereby a downwardpressure willbe directed to that wheel in order that the ,same willberetained upon its rail` during the raising of the journal box forreplacement of the bearing.

Othery objects of the inventionwill be in part obvious and in partkpointed out hereinafter.

In order that the invention and its mode of operation may be readilyunderstood by persons skilled iny theart, I have in the accompanyingillustrative drawings, and in the detailedy following description basedi0 thereupon set out one possible embodiment `of the same. v

In these drawings z-r Figure 1 1s a side elevation ofthe improved jackhaving a portion of the anchor- 5 ing means broken away and shown insection and also, the anchoring leg engaged with the vinner peripheralsurface of a car wheel, and l i f l Figure 2 is a side. elevation of theim- 0 proved jack having portion broken away.

. Having more particular referenceto the drawings, invconnection withwhich like .characters of reference will indicate corresponding partsthroughout, it is to be ,un-

i derstood that my invention resides primarily in' thewprovision of anattachment forrailwayjacks whereby said jacks-will serve to direct adownward pressure or stress u on an adjacent portion of a car wheelwereby tol retain said wheel upon its track during the raising of thejournal box thereof for `the replacement of bearings in the same. Tothis end, the invention therefore temp,risesE certain novel meansVwhia'e'li tha-.y

be attached to various or different forms or designs of railway jacksnow prevalent inthe art.

f For purposes of illustration, I have shown my invention as beingapplied to a form of railway .jack identified herein in its entirety -bythe numeral l, said jack comprising a body or casing portion carriedupon ay suitable base 2 while a screw threaded rod or shaft 3 extendsfrom the upper e-nd of this body portion or casing and carries the usualsaddle or head 4 thereupon adapted to be engaged under the object to beelevated or jacked. Suitable operating means are connected orconnectible with the screw threaded rod or shaft 3 whereby to effect theraising and lowering` of the same together with the saddle or head 4.

The invention may be 'stated to comprise an outwardly curved anchoringleg 5 having an attaching bracket 6 pivoted to the inner end thereof asis indicated at 7 while the outer or free end of said leg 5 is providedwith an outwardly curved or laterf ally offset foot 8 carrying upon itsupper side and adjacent its point of jointure with the leg 5,-relativelyspaced apertured ears 9 for a purpose which will be presently described.

When pivotally connected to the lower portion ofy one `side of thecasing or body portion of the jack 1 as is shown in the Figure 1, thecurved anchoring leg 5 is adapted vto be swung toward and away fromlsaid body portion of the jack so that, at times, the outwardly curvedor laterally offset foot 8' will be brought into engagement with a.portion of the inner peripheral surface of a` car wheel 10 resting uponthe usual railway track l1, such car-wheel having its axle received inthe usual journal box l2 in which bearings are arranged and retained.

In the replacing of worn bearings in journal boxes such as indicatedherein by the numeral l2, it is the practice to eect such replacementwhile the railway cars are upon their tracks, such as indicated at 1land therefore, the prevalent practice is to first connect or anchor thecar wheel l0 to its particular track 11 by a. clamp or similarconnection whereupon a jack is placed upon an adjacent rail tie or othersurface and is operatedv so that the saddle 4 thereof will be movedupwardly into'endagement with and will elevate-the jaartal-ctw 12 to apoint loo whereat the worn bearings may be conveniently removed andreplaced by new ones. Such practice, however, involves additional andexcessive labor upon part of workmen engaged in the operation andlikewise, is absorbing of considerable time. Therefore, with a viewtoward providing the anchoring leg 5 of my invention with means formaintaining the same in an engaged position with one portion of theinner peripheral surface of the car wheel 10 and also, for directing adownward stress to said leg 5 and foot 8 which will be sufficient toretain the car wheel 10 upon its track 11, I provide the device withlongitudinally aligned screw threaded rods 13 and 14, engaging upon theupper end of the rod 13 and attaching plate 15 adapted to be fixedlysecured to the aforesaid side of the body ortion or casing adjacent theupper end t ereof as is shown in the Figure 1; apertured bearing ears 16being formed upon the plate whereby to permit of pivotal connection ofsaid end of the rod 13 thereto as indicated by the numeral 17. Theopposite or outer end of the rod 14 is also provided with an aperturedextremity adapted to be received between the apertured ears .9 formedupon the upper side of the foot 8 whereupon a pivot pin 17 is passedtherethrough, hence, effecting pivotal connection as between the leg andfoot and the rod 14. A turnbuclrle 18 is engaged with the adjacent screwthreaded portions of the several rods 13 and 14. It is obvious that withturning of the turnbuclile 18, the screw threaded rods 13 and 14 may bedrawn together or forced apart with respect to each other, hence,imparting during such operation, pivotal movement to the foot carryingleg 5.

In usage of the improved jack equipped with the invention, the ack isplaced in position as is shown in the Figure 1, directly beneath thejournal box 12 which is to be raised and to have bearings replacedtherein. The leg 5 with its outwardly curved foot 8 is positioned so asto be arranged in proximity to the car wheel l() and with thispositioning, the turnbuckle 1S is rotated in a direction to causerelative outward movement upon part of the several rods 13 and 14,hence, moving the foot 8 of the anchoring leg 5 downwardly intoengagement with a portion of the inner peripheral surface of the carwheel 10 as is shown in the Figure 1. The said foot 8 is engaged withthe inner peripheral surface of the car wheel 10 under a pressuresufficient to absolutely insure the retention of said car wheel upon itsrail 11 irrespective of the direction of upward stresses or liftingmovement to the journal box 12. Subsequently to proper anchoring of thecar wheel 10 upon its rail 11, the rod 3 is elevated so as to bring thesaddle 4 thereof into engagement with the journal box 12 whereupon saidjournal box will be raised to a pointwhereat convenient access may behad to the worn bearings therein, following which such bearings may bereadily removed and replaced by others. During elevation of the journalbox 12, that is, in the process of replacement of the worn bearingstherein, it will be understood that the car wheel 10 will be preventedfrom having any vertical niotion or movement whatsoever with respect tothe rail'll, since, as aforesaid, theleg 5 with its outwardly curvedfoot 3 is engaged with said car wheel under a pressure sufficient toabsolutely insure retention of this latter upon its rail. Likewise, itwill be appreciated that the positive engagement as effective betweenthe foot carrying leg 5 and the car wheel 10 will be such as topositively locate the jack body portion or casing against undesirableshift-ing movement, dur-- ing that period of its initial engagement`with the under side of the journal box 12.

Thus, it will follow that an effectual raising of the journal box 12upon the shaft 3 and sat dle 4 of the jack will result.

Then replacement of the bearings in the box 12 has been effected, theshaft 3 is operated in a manner to return the same to its lnormal orlowermost position with respect to the journal box 12 hence, permittingthe bearings in said box to be re-engaged with the car wheel axle. Atthis time, the turnbuclde 13 is rotated in 'a reverse direction fromthat hereinbefore described, causing the screw threaded rods 13 and 14to be moved in a direction toward each other and by consequence,removing the outwardly curved foot 8 of the leg 5 from the previouslyengaged inner peripheral portion of the car wheel 10.

By reason of the fact that this anchoring attachment is connected to ajack through the medium of the attaching plates G and 15, it will beunderstood that such device may be successfully used in connection withvarious forms or types of jacks now generally in use for this particularpurpose, without in any way effecting material modification thereof.

Manifestly, the construction shown is capable of considerablemodification, and such modification as is within the scope of my claim,I consider within the yspirit of my invention.

In combination with a jack of the character described, an anchoring legcuived upon itself throughout its length and having an acutely curvedand out vardly disposed foot formed integral with the outer end thereof,the fiee extremity of said foot being rounded and being so disposed asto directly engage with an adjacent portion of the inner peripheralsurface of a car wheel,
